It serves for communication with the iNELS system via commands sent in short SMS messages from mobile phone GSM.
With the GSM3-01M and a smartphone, it is possible by SMS message or a call to control the iNELS system or obtain information on its status and current events.
By means of the software iDM3, you can use up to 8 incoming calls, 8 outgoing calls, 32 incoming SMS messages and 32 outgoing SMS messages.
For SMS messaging, the message length is limited to 32 characters, and for each message, you can set up to eight telephone numbers. In total, it is possible in iDM3 to use up to 512 telephone numbers.
One telephone number can be set for each incoming and outgoing call.
The maximum length of an incoming call is around 30s, and then the GSM3-01M hangs up. The user can set the length of outgoing calls in the software iDM3.
GSM3-01M can be used for informing users about any system status, e.g. in the event of a fault in some technology or building interference.
Operating range is 850, 900 as well as 1800, 1900 MHz (quad-band).
SIM card is inserted into the unit from the front panel.
The MINI USB connector on the front panel is used for servicing, but confi guration of telephone numbers, SMS messages and calls is done from the software iDM3.
GSM3-01M connects to the central unit CU3-01M (02M) via the EBM system BUS (terminals EBM+ and EBM-).
In case it involves the last unit on the system BUS EBM, it is necessary to terminate the wire with a resistor with rated resistance of 120Ω. This part adapted to be inserted between terminals is included into central units packages and it is necessary to insert between terminals EBM+ and EBM-.
The package includes is an external magnetic antenna (cable 3m, 5db gain), which is connected to the connector RSMA (F) on the front panel.
GSM3-01M in 3-MODULE version is designed for mounting into a switchboard, on DIN rail EN60715.
